SAFE-BOLTWORK.

SPECIFICATION forming part of Letters Patent No. 621,122, dated March14, 1899.

Application filed October 13, 1898. Serial No. 693,468. (No model.)

from the following description, taken in connection with theaccompanying drawings, in which Figure 1 is an elevation of the innerface of a safe-door provided with boltwork exemplifying my presentimprovement, while Fig. 2 is a side elevation of the upper bolt and itsattachments.

In the drawings, 1 indicates the door, provided with the usualbolt-frame; 2, the upper horizontal bolt; 3, the lower horizontal bolt;4, the hinges; 5, the carrier-bar rigidly connected to the twohorizontal bolts; 6, the carrier-driver, projecting rigidly from thecarrier-bar between and parallel with the horizontal bolts; 7, thestop-screw engaging a slot in driver 6 and limiting its stroke; 8, thelock; 9, the lock-bolt; 10, the bolt-spindle, all of the parts thus farreferred to being of usual construction and arrangement; 11, ahorizontal lever secured on the-inner end of the boltspindle, so as tobe oscillated by it, one horizontal arm of the lever projecting from thelock-spindle 10 toward the lock 8, while the other horizontal armprojects from the lockspindle in the opposite direction; 12, a lug onthe inner end of the lever 11 and adapted to sweep up and down in frontof the end of the retracted lock-bolt 9 in the act of throwing the boltsfrom projected to withdrawn position and to rest over lock-bolt 9 whenthe doorbolts and the lock-bolt are in thrown position, whereby thedoor-bolts can be withdrawn only after the lock-bolt has been withdrawn;13, a knuckle formed on the vertical third arm of the bolt-spindle 10,this knuckle en gaging a knuckle-notch in driver 6, so that oscillationsof lever 11 will shoot and retract horizontal bolts 2 and 3; 14:, thelower vertical bolt; 15, a shank projecting upwardlyfrom that bolt intopivotal connection with the outer horizontal arm of lever 11; 16, theupper vertical bolt; 17, a slotted eye at an intermediate portion ofbolt 16 where it inter sects with bolt 2 to permit these two bolts tohave their movements without interfering with each other, shank 15 beingalso slotted at its intersection with bolt 3, and 18 a link pivotallyconnected with the lower end of bolt 16 and the-inner horizontal arm oflever 11.

The oscillation of lever 11, as produced through the medium of thebolt-spindle 10, brings about the projection and retraction ofhorizontal bolts 2 and 3 and simultaneously the projection andretraction of bolts 14 and 16. All the bolts are in the same verticalplane, and the'slotted eyes in the vertical bolts permit the bolts tomake their move men ts without interference. It is immaterial whetherthe slotted eye be formed through the body of the bolt or its shank, asin the 1 case of the lower bolt 14, or be formed by an extraenlargement, as shown in connection with bolt 16. Link 18 permits bolt16 to have a vertical motion practically uninfluenced by the fact thatbolt 16 is operated from a pivot moving in the arc of a circle, and, ifdesired, such link may be applied to the lower vertical bolt also. Bolt14 duringits reciprocations obviously partakes of a lever-like motion,its bearing in the bolt-frame forming the fulcrum, and it is obviousthat this bearing must be free enough to permit the reciprocation of thebolt without detrimental binding, and it is also obvious that the boltmust enter its locking-socket with sufficient freedom to be uninterferedwith by this lever-like motion.

I claim as my invention In safe boltwork, the combination, substantiallyas set forth, of a door, a bolt-frame, a vertical bolt and a horizontalbolt intersect ing each other in a common vertical plane, one of saidbolts being provided with a slotted eye surrounding the other of saidbolts, and mechanism for throwing said bolts simultaneously.
